Written by

Anker PowerCore II 20000 is the 2nd generation which combines ultra-high power-capacity, super-fast charging and recharging, with triple-output USB ports. The PowerCore II 20000 offer huge 7-day charge capacity, triple-device charging and the new dual micro USB Input that means 2x faster recharge than the 1st generation!

Anker PowerCore II 20000 looks a lot smaller in real life and seems pretty solid. Its minimalistic black casing, not glossy, helps it to slip away without drawing too much unwanted attention. The plastic is very solid, it doesn’t make any noises when we squeeze or try to warp it.

There are dual micro USB ports on the side of the device which allow for a huge 20W input. You need to have a compatible charger and 2 cables to take advantage of its double-speed recharging features which recharge in half the time of comparable portable chargers. It has 3 USB charging ports offer triple-device charging simultaneous, high-speed charging for any three USB devices. Saving you time with every charge.

PowerCore II 20000 features

The PowerIQ technology works really well. It cleverly identifying, recognizes any connected device for and delivers the optimum, high-speed charge as possible to all devices. Includes Apple and Android phones and tablets as well as cameras, consoles and more. However, this isn’t anything special as it included with the entire Anker product line.

The only down side is that it doesn’t support passthrough charging, which enables you to power up both the power bank and any connected devices from a single mains outlet, but Anker says this feature has been disabled to avoid any negative impact it may have on the battery.

Overall, Anker PowerCore II 20000 is the best in class of power bank 20000mAh with ultra-high capacity, super-fast charging, 2x faster recharge and triple-device charging simultaneous. You can’t go wrong with this latest evolution of the world-famous PowerCore series. All-new look, more power, more speed and more ports!
